Disclosed is a machining method for a rolling bearing with a ring precisely shaped by hard finishing. The machining method is characterized in that an inner ring and an outer ring of the bearing are integrally precisely shaped by hard finishing or the key surface of a ring part is precisely shaped by hard finishing; the key surface comprises raceways, raceway flanges, raceway oil grooves, seal grooves, ring flanges, grooved raceway edge chamfers and the like; precise shaping by hard finishing takes the place of grinding (such as the raceways) shaping and shaping by soft finishing (such as the sealing grooves), so that technical and quality problems of limited shape design of a raceway section, grinding badness even burn injuries and the like are solved; the technical and quality problems of low machining precision, heat treatment distortion and the like existing in shaping surfaces of the sealing grooves, the grooved raceway edge chamfers and the like by soft finishing are solved by precise hard finishing, so that the surfaces of the ring can be designed according to the operating condition and can be shaped precisely in a quite high mode, and the key surface of the ring can be controlled in shape and performance, and designing and manufacturing of the high-performance rolling bearing high in sealability and reliability and the like are of great practical engineering significance.

Cellfree adipose tissue extracts, implants including the same and methods for the preparation thereof. The extracts and implants are capable of inducing adipogenesis and angiogenesis and are, thus, useful in applications including soft tissue repair and engineering and angiogenesis induction, e.g., in wound healing, treatment of burn injuries and ischemic conditions.

The invention provides a cyclic polypeptide of Formula I (SEQ ID NO: 1):X1-R-X3-X4-L-S-X7-X8-X9-X10-X11-X12-X13  Ior an amide, an ester or a salt thereof, or a bioconjugate thereof, wherein X1, X3, X4, X7, X8, X9, X10, X11, X12 and X13 are defined herein. The polypeptides are agonist of the APJ receptor. The invention also relates to a method for manufacturing the polypeptides of the invention or bioconjugates thereof, and their therapeutic uses such as treatment or prevention of acute decompensated heart failure (ADHF), chronic heart failure, pulmonary hypertension, atrial fibrillation, Brugada syndrome, ventricular tachycardia, atherosclerosis, hypertension, restenosis, ischemic cardiovascular diseases, cardiomyopathy, cardiac fibrosis, arrhythmia, water retention, diabetes (including gestational diabetes), obesity, peripheral arterial disease, cerebrovascular accidents, transient ischemic attacks, traumatic brain injuries, amyotrophic lateral sclerosis, burn injuries (including sunburn) and preeclampsia. The present invention further provides a combination of pharmacologically active agents and a pharmaceutical composition.

The invention discloses a 3D printer with a finished product fast taking-out function. The 3D printer comprises a 3D printer body. A pair of strip-shaped grooves is formed in the lower wall face of a printing platform of the 3D printer body. Strip-shaped sliding rails are embedded in the strip-shaped grooves. A pair of moving wheels is assembled on the strip-shaped sliding rails. Support seats are installed on the upper wall faces of the moving wheels. Bearing plates are installed on the upper wall faces of the two pairs of support seats. First strip-shaped support seats are fixed to the upper wall faces of the bearing plates. The side wall faces of the first strip-shaped support seats are provided with first grooves. First swing motors are installed in the first grooves. First support rods are installed at the driving ends of the first swing motors in a sleeved mode. Arc-shaped art knives are installed on the first support rods in a sleeving mode. The 3D printer is novel in structure and convenient to operate, and effectively helps people to take out a formed article printed by the 3D printer, taking of the finished product saves time and labor, loss of the finished product due to inconvenient taking is reduced, and meanwhile, the phenomenon of burning injury of people is reduced.
